DIAGNOSTICS & TROUBLESHOOTING
DIAGNOSTIC GUIDE
Before servicing, check the following:
•
Make sure there is power at the wall
outlet.
•
Has a household fuse blown or circuit
breaker tripped? Time delay fuse?
•
Are both hot and cold water faucets open
and water supply hoses unobstructed?
•
All tests/checks should be made with a
VOM or DVM having a sensitivity of 20,000
ohms per volt DC or greater.
•
Check all connections before replacing
components. Look for broken or loose
wires, failed terminals, or wires not pressed
into connections far enough.
DIAGNOSTICS
•
A potential cause of a control not functioning
is corrosion on connections. Observe
connections and check for continuity with
an ohmmeter.
•
Connectors: Look at top of connector.
Check for broken or loose wires. Check
for wires not pressed into connector far
enough to engage metal barbs.
•
Resistance checks must be made with
power
and with wiring harness or connectors
disconnected.
